If you want to write -5 x -5 as an exponential equation, you would write it as (-5)^2. In mathematical convention, a negative number raised to a power is negative -- implied in "5^2" is "-1 x 5^2", or -25. So the answer to the question is 50.

Mathematical convention??? Not in this Universe where most of us live.

Your TI-84 is wrong.
-5^2 = 25......-1 x 5^2 = -1 x 25 = -25....(-1 x 5)^2 = 25
5^2 implies -1 x 5^2 ????.... In other words, every single time you square a positive number you get a negative number?

Lol — I still cringe whenever I see someone using a calculator without RPN. The fact that HP CEO Carly Fiorina tried to kill off RPN calculators told me all I needed to know about her ability to lead in government or industry.

You can have my HP-15C when you pry it from my cold dead hands.
That equation, as it is written, would equal to 0.
Not even sure how there is debate about this..
